A short, efficient and general methodology for benzo[b]carbazolenaphthoquinones was developed via Pd‐catalyzed C‐H arylation process. This methodology was successfully applied to the synthesis of highly biologically active compound 5H–benzo[b]carbazole‐6,11‐diones. Additionally, one‐pot synthesis of benzo[b]phenazine‐6,11(5H,12H)‐dione derivatives was also explored in aqueous medium.
通过Pd催化的CH-H芳基化过程,开发了一种简短,高效且通用的苯并[ b ]咔唑萘醌方法。该方法已成功地用于合成具有高生物活性的化合物5H-苯并[ b ]咔唑-6,11-二酮。此外,还研究了在水介质中一锅法合成苯并[ b ]吩嗪-6,11(5H,12H)-二酮衍生物。
